Log Files Wanted for Drop Rate Analysis

Archie Gremlin · 10-01-2009 04:37 AM

Hi Folks,

Now that the drop rate bug seems to have been fixed, I'm keen to work out the drop rates for purples, pool C/D boss drops etc.

I need lots of log data to do this with any degree of accuracy so I'm asking for help. I'd be most grateful if you could enable chat logging and then send me the log files.

You don't need to log anything special but solo play is much for useful than team play. Any level, AT etc is fine.

You can find full details on the DropStats website here.

I'll post my findings as soon as I have anything useful to report.

(Please feel free to send log files by other any method you like if you don't fancy email.)

many thanks,
Archie

I'll be sending some your way, probably at the weekend.

Would you prefer a large log of several missions, or logs split out by individual missions ?

Thanks Cat.

It doesn't matter how many files you send or how much stuff is in each file. Just send whatever's most convenient for you.

Would you rather have the logs sent to you or should we try to compile the data in this thread? I only ask because in my mind the more eyes on it the better, but either way I'll help as I can.

AgentMountaineer · 10-01-2009 05:43 AM

Good to see you working on this, Archie. I just shot you an e-mail of my log from last night running the Mender Silos TF.

Please send me the files themselves. This allows me to analyse them in all sorts of ways including some I haven't thought of yet! It also avoids the problem of different people reporting different things.

Collecting stats in a thread seems like a good idea too. Maybe someone would like to kick that off.

Zyal · 10-01-2009 06:03 AM

Oooh this sounds like a fun task
I'll start collecting data too this weekend.

I have gone to find myself. If I get back before I return, Keep me here!

I never did get drops stats to work, it just looked like two text files after I unzipped it. After spending the entire work day in front of a PC my brain is mush. I'll read the instructions on Monday as that will be my next chance to really play.

Again thanks for creating this program!

Who do I have to *&^% around here to get more Targeted AoE recipes added?

In this case, you don't need to be able to run DropStats to help. I'm just after the log files that CoX produces when you turn on chat logging.

Just in case you don't know...

You can turn on chat logging by going in to Menu | Options menu. Select the General tab, and scroll down to the Chat section. The setting you need is "Log Chat". When it's enabled it will start logging your game play. It saves the logs in the "logs\game" folder in your CoX installation. Those are the files I'd like to see.

I've recently added much more detailed instructions to the website for installing PERL and using the Command Prompt. I hope that'll help.

If you're still stuck when you've had a chance to try it again then please PM me. I'll be happy to help.

And yes... at one point it did indeed just look like a couple of text files.

Kitteh · 10-01-2009 07:35 AM

Thanks, Archie!

I'll send you Sept 30th (all data was post-patch) and Oct 1st (got a AA purple this morning before work) when I end my play session tonight.

Going forward, I'll send you whatever "solo @ level 50" logs I have on Mon and Thu nights.

So I just had to wonder if you'd taken 2XP weekend into consideration...I don't think the heuristic rank checks are going to be happy about that.

Same here will be mostly solo red side

Aargh!

You're quite right. I'll have to figure out how to account for that.

If you don't get find the value, try looking for 1/2 of it?

Some early results from around 4,000 defeats...

The Pool A recipe and salvage drop rates appear to match the Wiki values. (Although the margin of error is quite large at the moment.)

Pool A average is 2.75% with 95% confidence interval of 2.3% to 3.3%.
Salvage average is 7.96% with 95% confidence interval of 7.2% to 8.8%.

Tier 1 and Tier 2 inspirations have a drop rate of around 30%. The ratio of Tier 1s to Tier 2 is about 2:1. Tier 3 inspirations don't seem to drop from minions or lieutenants.

It's still too early to say anything about Pool C/D boss drops or purples. (More data please!)

This is correct. They only drop from things of boss rank or higher.

I'm working on data from hero stats. When I get more I'll send it your way, so far up to a little under 8000 defeats and 1 purple drop. (Ouch?) I was after about the same thing, to see where the drop rate was after it was fixed. Hopefully you can use it as I'm not all that familiar with the difference between it and dropstats.

Here's some tables for inspiration drops based upon I7 data, which may or may not still be accurate. It doesn't include the actual chance of a drop, though.

Thanks. I wasn't aware of that.

DropStats works from the log files that CoX produces when you turn on chat logging. If you've got those files then I'd love to have them. If not, then please consider turning on chat logging and then sending me the files.

Hero Stats creates it's own files. They actually contain all the information that's in the CoX log files but in a different format. DropStats can't read them at the moment. (But it might be able to in the future.)

MrLiberty · 10-03-2009 03:14 PM

Cool! As I plan to run this for a month - ish I'll definitely go ahead and turn the log files on. (I need to restock my purple bin) Do I need to run drop stats at all times or can it retroactively go back and pull from the logs what you need?

UberGuy · 10-03-2009 04:28 PM

It's an offline parser. He just needs to feed it the log files. Nothing to run while you play.

Dropped an email to you with a small sample chat log. Only like 4 Battle Maiden runs. I'll have more time to play Sunday so I should be able to get in 20-30 runs or more for ya.

firespray · 10-04-2009 05:23 AM

I'll start doing this and send you some log files as well.

Leandro · 10-04-2009 11:17 AM

Sent 2026 solo defeats your way. One purple in there.
